Návrh algoritmů číslicového zpracování signálů pro simulaci kytarových zesilovačů založených na obvodové analýze analogových prototypů / Design of Algorithms of Digital Audio Processing for Simulation of Guitar Combo Based on Circuit Analysis of Analogue Prototypes

Mačák, Jaromír January 2008 (has links)
This work deals with computer simulation of a guitar combo. The complete simulation is divided into separate blocks and then transfer characteristics and frequency responses of each block are obtained from a circuit analysis of analogue prototype. After their aproximation, the transfer characteristics are implemented as waveshapers and frequency responses are simulated using digital filters designed according to their analogue prototypes. Designed algorithms are implemented as plug-in mudule in language C++.

Vliv přesnosti aritmetických operací na přesnost numerických metod / Numerical Methods Accuracy vs Precision of Arithmetic

Kluknavský, František January 2012 (has links)
Thesis is dedicated to evaluation of roundoff impact on numerical integration methods accuracy and effectivity. Contains theoretical expectations taken from existing literature, implementation of chosen methods, experimental measurement of attained accuracy under different circumstances and their comparison with regard to time complexity. Library contains Runge-Kutta methods to order 7 and Adams-Bashforth methods to order 20 implemented using C++ templates which allow optional arbitrary-precision arithmetic. Small models with known analytic solution were used for experiments.

Modelování a HIL simulace ovládání pátých dveří osobního automobilu / Modelling and HIL Simulation of Vehicle Boot Door Control

Musil, Filip January 2017 (has links)
This diploma thesis focuses on an analysis, a model creation and simulations of a car boot door mechanism. The problem was analyzed on the basis of real measurements made on three different vehicles. Based on the measurements, computational models describing the real system at different levels of complexity were created. Matlab/Simulink was used to create and calculate the models. The output of the thesis is the simulator of a car boot door which also includes simplified model of a control unit. The simulator should provide an approximation of current and kinematic quantities of these mechanisms. The model is implemented on dSPACE platform that allows real-time simulations. The simulator can be modified in terms of changing the parameters of the mechanism and modifying some of its results.

Analýza transportu vzdušné vlhkosti v obalových konstrukcích budov / Analysis of humid air transport in the building envelope

Tománek, Jan January 2018 (has links)
The diploma thesis deals with the analysis of temperature and humidity in the construction of flat roofs with influence even without influence of solar radiation. It was necessary to study and verify the properties of building materials, the physical nature of the influence of solar radiation on building structures and the transport mechanisms of moisture. The theoretical part describes the basic physical theory on solved problems, the essence and division of solar radiation, the description of thermal moisture properties of building materials and the calculation method of determination of moisture in structures according to valid standards. Practical part deals with description of work in software DEKSOFT - Thermal technology 1D and WUFI 2D software, description of individual models and analysis of achieved results. At the end of the practical part the achieved theoretical knowledge is validated by analyzing the obtained data from the practical model.

Simulace kapalin na GPU / Fluid Simulation Using GPU

Frank, Igor January 2021 (has links)
This thesis focuses on fluid simulation, particularly on coupling between particle based simulation and grid based simulation and thus modeling evaporation. Mentioned coupling is based on the article Evaporation and Condensation of SPH-based Fluids of authors Hendrik Hochstetter a Andreas Kolb. The goal of this thesis is not purely implementing ideas of the mentioned article, but also study of different methods used for fluid simulation.

Částicové simulace v reálném čase / Real-Time Particle Simulations

Horváth, Zsolt January 2012 (has links)
Particle simulations in real-time become reality only a few years before, when in computer science occured the idea of GPGPU. This new technology allows use the massive force of graphics card for general purposes. Today, the trend is to accelerate existing algorithms by rewriting into parallel form. On this priciple operate the particle systems too. An interesting area of particle systems are fluid simulations. The simulations are based on the theory of Navier-Stokes equations and their numerical solutions with SPH (Smoothed particle hydrodynamics). Liquids are part of everyday life, and therefore it is important to render them realistically. They are used in modern computer games and different visualizations that run in real time, therefore they must be quickly displayed.

Modelování IPv6 v prostředí OMNeT++ / IPv6 Modelling in OMNeT++

Černý, Marek January 2011 (has links)
OMNeT++ is a discrete-event simulator commonly used to build various network simulations. It can be extended by INET framework that supplies models of protocols and devices from TCP/IP environment. This paper explores current capabilities of INET to model IPv6, particularly routing. Implemented extension includes modules of dual-stack router and dual-stack host that support XML-based configuration of IPv6 addressing and static routing. We also introduce an OSPFv3 module that implements most of auxiliary features and is ready for future development of the routing protocol core.

Simulátor městské dopravy / City Traffic Simulator

Dostál, Martin January 2016 (has links)
This thesis is focused on microsimulation of city traffic, specifically a small city circuit in Brno. The thesis describes approaches for solving the problem of road network representation and presents basic methods and models needed for traffic simulation on the level of individual vehicles control as well as on the level of simulator control. In the case of more possible solutions to the given problem, the features and suitability of these solutions are compared. In the practical part of the thesis, the structure of the proposed simulator is presented with all the dependencies among individual submodels, along with the description of implementation details related to the individual parts.

Možnosti využití nových medií v oblasti formálního vzdělávaní: Případová studie návrhu historické simulace / The use of new media in formal education: A case study of design of the historical simulation

Lekovski, Michael January 2012 (has links)
Thesis was developed as a model specification for a design of historical simulation applied in formal education. The text is divided into two main parts: The theoretical part summarizes findings about the role of new media in e-learning and its potential enrichment for gamification elements. Also mentions computer game as a research subject and points to the game mechanics that can be used in formal education to a successful application DGBL - Digital Game-Based Learning in this process. Practical part presents case study of a model specification that is based on the real project: 'Stories from the History of Czechoslovakia: Research and experimental development of software simulations to teach the history of the Czech lands in the 20th Century", solved by Faculty of Arts and Facility of Mathematics and Physics of Charles University and Institute of Contemporary History of Academy of Sciences of Czech Republic in Prague in 2011- 2014. In this section are addressed by specific examples of model applications of gamification elements with a view to achieving the educational goals of teaching simulation.
